Abstract

A device for measuring current is connected to a data processing apparatus loaded with a current value comparison program for performing a quality test on a portable electronic apparatus with a battery. The portable electronic apparatus has a battery compartment for receiving the battery. The device for measuring current includes: a power supplying module for generating a low-voltage current; a dummy battery with a shape of the battery for inserting into the battery compartment, the dummy battery electrically connected to the power supplying module and the portable electronic apparatus to provide the low-voltage current generated by the power supply module to the portable electronic apparatus, forming a power supply loop to the portable electronic apparatus; and a current measuring module electrically connected to the power supply loop for measuring a current value of the power supply loop when the portable electronic apparatus is performing a specific function and transmitting the measured current value to the data processing apparatus for comparison. The present invention does not heavily rely on manual operations to measure the current of the portable electronic apparatus.

Description

FIELD OF THE INVENTION[0001]The present invention relates to devices for measuring current, and more particularly, to a device for measuring current of a portable electronic apparatus with a built-in battery.BACKGROUND OF THE INVENTION[0002]Generally, manufacturers of electronic devices perform a series of tests on their products before shipping or mass production in order to provide consumers with good-quality products. Among them, one of the tests determines whether current consumptions of a portable electronic apparatus (e.g. a palm computer or smart phone) under different operating conditions are all within their ideal ranges, so as to detect any faulty products at an earlier stage.[0003]Specifically, testing personnel connects a portable electronic apparatus to be tested to an external power supply, and connects a digital multimeter to the power supply. Then, the power supply is operated to provide a low voltage to the portable electronic apparatus, and the portable electronic ...
